Get priceA rotation is when the planet spins around once. The Earth rotates counterclockwise this is why the Sun "rises" in the East and "sets" in the West. It is not the Sun''s movement that causes days, but rather the Earth turning around in front of the Sun.

Get priceWhat is the speed of the Earth''s rotation? At the equator, the circumference of the Earth is 40,070 kilometers, and the day is 24 hours long so the speed is 1670 kilometers/hour ( 1037 miles/hr). This decreases by the cosine of your latitude so that at a latitude of 45 degrees, cos(45) = .707 and the speed is .707 x 1670 = 1180 kilometers/hr.
